2014-05-22Add APT::Acquire::$(host)::By-Hash=1 knob, add Acquire-By-Hash to Release fileMichael Vogt
The by-hash can be configured on a per-hostname basis and a Release file can indicate that it has by-hash support via a new flag. The location of the hash now matches the AptByHash spec

2014-05-22Implement simple by-hash for apt updateMichael Vogt
This implements a apt update schema that get the indexfiles by the hash instead of the name. The rational is that updates to the archive servers/mirrors are not atomic so the client may have the previous version of the Release file when the server updates to a new Release file and new Packages/Sources/Translations indexes. By keeping the files around by their hash we can still get the previous indexfile without a hashsum mismatch. Enable with APT::Acquire::By-Hash=1

2014-05-14Pass struct IndexTarget/indexRecords to pkgAcqIndex{,Merge}DiffsMichael Vogt
If one of the pkgAcqIndex{,Merge}Diffs fails, they will run pkgAcqIndex() which needs the IndexTarget/indexRecords data. So we pass it along.
2014-05-12(try to) fix travis-ci build failuresDavid Kalnischkies
dpkg on Ubuntu 12.04 does not seem to support parsing arch-specific dependencies, so we try to detect if we face such a dpkg in the test. In the other test the order depends on libdb, which changes per arch, so we just run it through our sorting binary and be happy (hopefully). Git-Dch: Ignore
2014-05-10add an additional test for arch specific conflictsDavid Kalnischkies
In bugreport #747261 I confirmed with this testcase that apt actually supports the requested architecture-specific conflicts already since 2012 with commit cef094c2ec8214b2783a2ac3aa70cf835381eae1. The old test only does simulations which are handy to check apt, this one builds 'real' packages to see if dpkg agrees with us. Git-Dch: Ignore
2014-05-10invalid cache if architecture set doesn't matchDavid Kalnischkies
The cache heavily depends on the architecture(s) it is build for, especially if you move from single- to multiarch. Adding a new architecture to dpkg therefore has to be detected and must invalidate the cache so that we don't operate on incorrect data. The incorrect data will prevent us from doing otherwise sensible actions (it doesn't allow bad things to happen) and the recovery is simple and automatic in most cases, so this hides pretty well and is also not as serious as it might sound at first. Closes: 745036
2014-05-10improve pkgTagSection scanning and parsingDavid Kalnischkies
Removes the 256 fields limit, deals consistently with spaces littered all over the place and is even a tiny bit faster than before. Even comes with a bunch of new tests to validate these claims.
2014-05-09parse and retrieve multiple Descriptions in one recordDavid Kalnischkies
It seems unlikely for now that proper archives will carry multiple Description-* stanzas in the Packages (or Translation-*) file, but sometimes apt eats its own output as shown by the usage of the CD team and it would be interesting to let apt output multiple translations e.g. in 'apt-cache show'.
2014-05-09reenable pipelining via hashsum reordering supportDavid Kalnischkies
Now that methods have the expected hashes available they can check if the response from the server is what they expected. Pipelining is one of those areas in which servers can mess up by not supporting it properly, which forced us to disable it for the time being. Now, we check if we got a response out of order, which we can not only use to disable pipelining automatically for the next requests, but we can fix it up just like the server responded in proper order for the current requests. To ensure that this little trick works pipelining is only attempt if we have hashsums for all the files in the chain which in theory reduces the use of pipelining usage even on the many servers which work properly, but in practice only the InRelease file (or similar such) will be requested without a hashsum – and as it is the only file requested in that stage it can't be pipelined even if we wanted to. Some minor annoyances remain: The display of the progress we have doesn't reflect this change, so it looks like the same package gets downloaded multiple times while others aren't at all. Further more, partial files are not supported in this recovery as the received data was appended to the wrong file, so the hashsum doesn't match. Both seem to be minor enough to reenable pipelining by default until further notice through to test if it really solves the problem. This therefore reverts commit 8221431757c775ee875a061b184b5f6f2330f928.
2014-05-09tell download methods the expected hashesDavid Kalnischkies
Now that we have all hashes in the acquire system, pass the info down to the methods, so that it can use it in the request and/or to precheck the response.
2014-05-09promote ExpectedHashes to a pkgAcquire::Item memberDavid Kalnischkies
Beside being another big API break with hopefully zero fallout in reality it avoids having the same member and helper code in each and every subclass.
2014-05-09deal with hashes in ftparchive more dynamic as wellDavid Kalnischkies
Now that libapts acquire system happily passes around hashes and can be made to support new ones without an ABI break in the future, we can free ftparchive from all the deprecation warnings the last commit introduced for it. The goal here isn't to preserve ABI as we have none to keep here, but to help avoiding introduction problems of 'new' hashes later as bugs creep into the copy&paste parts, so short/less of them is good.
2014-05-09use HashStringList in the acquire systemDavid Kalnischkies
It is not very extensible to have the supported Hashes hardcoded everywhere and especially if it is part of virtual method names. It is also possible that a method does not support the 'best' hash (yet), so we might end up not being able to verify a file even though we have a common subset of supported hashes. And those are just two of the cases in which it is handy to have a more dynamic selection. The downside is that this is a MAJOR API break, but the HashStringList has a string constructor for compatibility, so with a bit of luck the few frontends playing with the acquire system directly are okay.
2014-05-09use 'best' hash for source authenticationDavid Kalnischkies
Collect all hashes we can get from the source record and put them into a HashStringList so that 'apt-get source' can use it instead of using always the MD5sum. We therefore also deprecate the MD5 struct member in favor of the list. While at it, the parsing of the Files is enhanced so that records which miss "Files" (aka MD5 checksums) are still searched for other checksums as they include just as much data, just not with a nice and catchy name.

2014-05-09add a simple container for HashStringsDavid Kalnischkies
APT supports more than just one HashString and even allows to enforce the usage of a specific hash. This class is intended to help with storage and passing around of the HashStrings. Git-Dch: Ignore
2014-05-09tests: be able to disable "Fetched …" statistics messageDavid Kalnischkies
The line contains everchanging execution statistics which is harmful for testcases as they need to filter out such lines, but this is hard so we can just add an option to disable them instead and be done. Git-Dch: Ignore
2014-05-08use a std::vector instead of hardcoded arrayDavid Kalnischkies
Arrays with predefined lengths are very fragile as they are likely forgotten in future changes and the size in this case is dynamic making it even more dangerous. Git-Dch: Ignore
